Description

Charge management method and system

The present invention generally relates to charge management of a rechargeable device.

For practical reasons (such as the need to exclude wires) and/or due to ease of use, the increasing number of devices used in the home and industry is manufactured in the form of electrically rechargeable devices (hereinafter also referred to as rechargeable). Or a charging device, for example for an electric vehicle). The charging device uses a rechargeable battery, or another type of electrically renewable power source as its main power source. An important use of rechargeable batteries is in the electric vehicle industry, which is intended to be gradually replaced by electric motor engine vehicles powered by rechargeable battery packs, or by so-called hybrid vehicles that utilize both internal combustion engines and electric motors. Gasoline and diesel internal combustion engine (ICE) vehicles that pollute the air.

Vehicles that are primarily used to transport passengers and cargo (such as cars, trucks, airplanes, ships, locomotives, automated vehicles, robots, pushers, etc.) have become an integral part of the modern economy. Most of the vehicles used today to transport passengers and cargo are powered by an internal combustion engine (ICE) that burns fossil fuels. Unfortunately, the use of fossil fuels (such as gasoline) has many shortcomings, such as the dependence on fossil fuels with limited sources (the source of exotic fossil fuels is usually in unstable geographical locations), and the pollution caused by their combustion (which causes the world warming).

Today, the transportation industry is encouraged to move to clean technologies that employ electric motors (also known as electric vehicles) powered by rechargeable fuel cells or batteries (herein referred to as rechargeable batteries). However, rechargeable batteries need to be recharged relatively frequently, and the charging point (also referred to herein as a charging electrode or charging device) for which the current is used to charge the battery of the carrier must be widely distributed and used for the vehicle. Can be used in as many locations as possible. For example, it may be necessary to charge the battery of the vehicle in a parking lot in a shopping mall or office building.

It is expected that as the use of electric vehicles increases, the current from the charging point location needs Demand will also increase, which may require a large increase in power supply facilities and increased power capacity to cope with the increase in charging current.

US 2011/133693 to Lowenthal Richard et al. describes an electric vehicle charging station that is coupled to a main circuit breaker in an electric maintenance panel installed in a user's home. The charging station described in this disclosure includes a current control device having a control preamble circuit that adjusts a pilot duty cycle to control the amount of current that the electric vehicle can draw from the service pull-down wire.

Therefore, when the demand for such charging power is increased, there is a grid management solution (also referred to as smart grid management) suitable for controllably managing the supply of charging power to a charging device (such as an electric vehicle). Demand. Accordingly, in some embodiments of the present invention, power based on the capabilities of the power network (grid), and also based on the need for charging power from a battery-related charging device, is provided to control the power being supplied to the battery being charged. Charging point.

Conventional charging points and charging devices associated with batteries for electric vehicles typically employ a signal transmission scheme that primarily involves adjusting the amount of charging current drawn by the charging device. However, since the demand for supplying charging power from the power network is increased, it is necessary to enable the charging point to controllably switch the charging power supply of the charging device connected to some of the carriers between the connected and disconnected states so as to be appropriately routed by the power grid. Manage the charging of most vehicles. The charging point according to a possible embodiment of the present invention is thus further configured to switch the charging power supplied to the battery of the charging device between turning on (ie, supplying charging power) and turning off (ie, wherein charging power is turned off), thereby providing Control of charging power supplied to the charging device by the power grid.

Preferably, the charging point of the present invention is configured to notify the charging device of the state in which it intends to switch the charging power supply, and thereafter to switch the state of the charging power supply only after receiving the confirmation indication from the charging device. In this manner, the charging point of the present invention can divide the charging session into a plurality of charging cycles. Each charging cycle may include a charging cycle initiated by the charging point and a charging cycle termination notification. Desirably, the charging point connects the charging power to the charging device only after receiving the charging cycle start confirmation from the charging device, and disconnects the charging power from the charging device after receiving the charging cycle termination confirmation from the charging device.

Conventional charging points utilize a preamble signal as defined in the standards used today to Receiving an indication from the charging device connected thereto and adjusting the charging power drawn by the charging device. However, these preamble signaling schemes do not provide support for allowing the charging point to indicate to its charging device that it is temporarily terminated or to resume charging power supply.

Although the charging point can forcibly terminate and restore the charging power supply, it is not appropriate to apply such switching when the vehicle actively draws current from the grid, and may have a negative impact on the charging point, such as shortening the average fault interval of the charging point components. Time (MTBF, mean time between failure). Furthermore, charging devices that are used in electric vehicles to manage battery charging are typically designed to treat sudden (unpredictable) removal of charging power as indicating the end of the charging session, and thus do not allow recovery of the charging session when charging power is reused.

Accordingly, there is a need for a system and method for reliably managing a charging session that allows a charging point to issue a signal indicating that charging will temporarily cease, and must remove the charging load before the charging power is electrically disconnected by the charging point. For example, for electric vehicles, such charging dialog management techniques can take into account many of the charging signal transmission schemes used in the charging of the vehicle battery and use signal transmission that is not standard with the field of charging for electric vehicle charging. Program.

The inventors of the present invention have discovered that a network comprising a plurality of communication coupled charging points can be used to effectively control the charging power supply supplied by the charging point. In a possible embodiment, the charging point includes a communication interface that is configured and operable to communicate with the central control system, and a conventional charging interface that is mechanically connectable to a charging device (eg, at least a portion of the electric vehicle). For example, in a possible embodiment, the charging point conforms to the IEC 61851 specification, which does not allow termination and/or recovery of the charging power supply initiated by the charging point, and therefore does not provide an allowable charging point to indicate that it is required to terminate the charging supply, or A signal transmission scheme that allows recovery of the charging supply after termination.

The inventors of the present invention have developed a charging session management signal transmission scheme that can implement a conventional communication method that conforms to a standard signal pre-signal line. In a possible embodiment, the charging session management signaling scheme is designed to allow the charging point to divide the charging session into a plurality of charging cycles by issuing a signal that it intends to temporarily terminate the charging cycle, thereby allowing the charging device to be electrically charged by the charging point. Remove the charging load before disconnecting the charging power supply. For example, in a possible embodiment, the charging point is used to indicate the end of the charging cycle after receiving information from the control system indicating that the charging power supply must be stopped.

In some embodiments, the charging session management signaling scheme utilizes definitions in the The preamble signal in the quasi-specification allows the charging point to emit a signal that will temporarily stop drawing the charging power to the charging device. For example, in a possible embodiment, the charging point issues a signal that it intends to stop charging power supply by driving a 5% duty cycle signal on the leading signal line. According to standard specifications, such a signal indicates that the charging device stops drawing charging power from the charging point and waits for the establishment of the series connection. This procedure allows the charging electrode to forcibly remove the charging load (ie, stop consuming charging power) before the charging point is electrically disconnected from the charging point to supply power.

In a possible embodiment, once the control system indicates that the charging point resumes charging, the charging session management signaling scheme is used to allow the charging point to resume the charging session. Typically, if the charging device needs to resume the charging session to further charge its battery, the charging session is resumed after receiving information from the control system indicating the level of maximum allowable power that the charging device can consume.

For example, pulse width modulation (PWM), which is conventionally used in the pre-signal of a standard charging point to indicate the maximum charging power that the charging device is allowed to draw, can be used in the charging session management signal transmission scheme of the present application to allow charging points. Indicates that the charging session can be resumed (ie by starting a new charging cycle). In particular, the charging session management signaling scheme of the present application can be configured to allow the charging point to set the duty cycle of the preamble signal by using a standard PWM duty cycle as defined in the standard specification ranging from 8% to 97%. The signal is used to encode the maximum charging current that can be initially supplied by the grid during the restarting charging cycle. Receiving a preamble signal, analyzing the received signal to determine its duty cycle, and the charging device based on the analysis draws the charging current by the allowable charging power level represented by the duty cycle of the received preamble signal (ie, Reconnect the charging load to the charging point) and start a new charging cycle.

In some possible embodiments, the charging session management signaling scheme is configured to allow the charging point to issue a fixed voltage signal (eg, 12V) to the charging device by providing a fixed voltage signal (eg, 12V) on the preamble signal line prior to electrically disconnecting the charging supply power. A signal that electrically disconnects the charging power supply is required. The charging device can interpret such a fixed voltage signal as a 100% duty cycle and stop responding to any charging power. Once the charging is allowed to resume, the charging session management signaling scheme can further be used to allow the charging point to provide an appropriate PWM preamble and thereby indicate to the charging device that a new charging cycle can begin.

In some other possible embodiments, the charging session management signaling scheme is used to allow the charging point to drive a PWM preamble of 0% duty cycle (eg, fixed -12V supply). The number is issued to signal that it needs to electrically disconnect the charging power supply (state F indicates that the charging point is not available for use).

In still other possible embodiments, the charging session management signaling scheme is used to allow the charging point to indicate that it intends to disconnect charging power by driving a 0 volt signal on the leading signal line.

In a possible embodiment, charging is allowed once by changing the duty cycle of the PWM preamble to indicate the maximum current that can be supplied from the grid (eg, using a duty cycle ranging from 8% to 97% as defined in the standard specification) The point continues to be charged (e.g., as indicated by the control system), and the charging session management signaling scheme is used to resume the charging session. In response, the charging device that senses a change in the duty cycle of the preamble signal can resume the charging session based on the allowable charging level encoded in the received PWM preamble.

The charging session in accordance with some embodiments may thus include a plurality of charging cycles. In each of these charging cycles, the supply of charging power can be initiated and terminated by the charging point using the signal indication defined by the charging session management signaling scheme of the present application. The charging session termination/recovery signal issued by the charging point is received by a charging device configured to terminate/restore the charging sequence (cycle) based on an indication encoding the received signal. Preferably, after the charging device stops capturing the charging current and sends the signal to the charging point, the charging connection (eg, charging line) for providing a mechanical and electrical connection between the charging point and the charging device can be mechanically disconnected. To terminate the charging session in such an embodiment.

Accordingly, the present invention, in some of its embodiments, allows the charging system to divide the charging session into a plurality of charging cycles. Optionally, the beginning and recovery of the charging cycle is based on data received by the charging point (eg, from the control system), which may include grid control/management instructions. The charging point can be configured to select at least one charging session management signaling scheme suitable for indicating the start and recovery of the charging cycle to the charging device, while employing a standard signaling scheme conventionally used in charging points. The charging session management technique of the present application can be used to charge a charging device configured to implement a conventional charging session as defined in the standard specifications by selecting a suitable charging session management signaling scheme. Therefore, the charging session of the present application (ie, managed by dividing the charging session into one or more charging cycles) can be used with minimal modification of the battery's charging configuration, or without any modification. It is known that the charging device (such as an electric vehicle that meets industry standard specifications) is charged.

For example, in accordance with some embodiments, each time the received power grid management command indicates that the supply of charging current should be stopped, the charging point issues a respective signal as defined by some embodiments of the charging session management signaling scheme of the present application. Instructs the charging device to stop drawing charging current from it. The charging device stops capturing the charging power after receiving the command signals, and then can send a signal to the charging point to indicate that the charging load is removed, and then the charging point terminates the charging cycle by electrically disconnecting the supply of charging power. A new charging cycle may be initiated by the charging point, for example, in accordance with the received grid management command that allows recovery of the charging power supply, and then the charging point may signal a maximum allowable level of allowable charging power to the charging device (eg, by charging) The dialog management signaling scheme is defined in accordance with some embodiments). In response, if the charging device needs to be further charged, it retransmits the charging load and draws the allowable charging power indicated by the charging point to signal that it intends to resume charging the charging power and resume the charging session, respectively (eg, The charging session management signalling scheme in some possible embodiments and/or as defined in the standard).

To fully charge a rechargeable battery, one or more such charging cycles may be required. Once the charging device determines that its battery does not require any further charging, the charging device electrically disconnects the charging load (ie, stops drawing the charging current) and indicates the charging point. The charging point is electrically disconnected to the charging device's charging power supply as a Respond. Thereafter, the charging session can be terminated by mechanically disconnecting the connection between the charging point and the charging device, such as a connector for charging the wire.

In some embodiments, the charging device can be used directly (eg, using wired communications such as using a data modem, a network adapter, or a parallel or serial data bus, or wirelessly using, for example, Wi-Fi, Bluetooth, or ZigBee). An on-board communication module that communicates with a charging point either indirectly (eg, using a data network, a cellular network, or via an operator server). For example, in an electric vehicle, an onboard communication module disposed in the vehicle can be used to communicate between the carrier and the charging point, and also with a central control center (eg, a service provider), and/or an operator. The server communicates. The vehicle can convey its clear brand and model to any entity that is communicatively coupled to it. The onboard communication module, operator server, or charging point of the vehicle can utilize the information conveyed to determine the specific vehicle support and the charging point can be used to indicate one of the charging cycles to start and resume or more suitable charging. Dialogue management signaling scheme. The charging point can then utilize the ability to determine one or more signal transmission schemes that are required to electrically indicate that the vehicle must be electrically disconnected from the charging load, and to restore charging whenever possible (eg, from a central control system, power based on the communication network) Supply network, service supply And/or individual indications received by the operator server).

In other possible embodiments, the user of the charging device may submit to the identification token (eg, an RFID card, a smart card, a biometric signature, and the like) before starting the charging session. The charging point is used for identification purposes. The identification credentials may include the identity of the user and/or identification data regarding the charging device. The identification credentials may further include further identifying information regarding the brand and model of the charging device, and/or regarding the charging session management signaling scheme supported by the charging device. The charging point can be configured to utilize information provided directly from the identification voucher, or by using it with a user stored in a control system (eg, hosted by an operator server) and/or its charging device The information in the library is cross-referenced to identify the charging session management signaling scheme supported by the charging device. Based on the information held in the database, the charging point can indicate to the charging device that the charging device must be disconnected from the charging supply using any of the charging session management signaling schemes described above, as well as the ability to resume the charging session (whenever possible) .

In some embodiments, the charging point is configured to employ a different charging session management signaling scheme in accordance with the signaling capabilities of the charging device. For example, some electric vehicles are configured to perform a charge plan that completely interrupts charging until the user restarts the vehicle whenever the number of times the charging power supply is interrupted is greater than a fixed number of times the charging power supply is interrupted by the charging schedule. The control point that senses the limit of the particular carrier in charging or controls the charging point can be configured to employ a charging session management signaling scheme that is configured to perform the carrier, and takes this information into account. For example, the charging point can adjust the charging session to include an electrical disconnection of the minimum number of charging power supplies to avoid exceeding the number of charging interruptions defined by the vehicle's charging schedule.

In some possible embodiments, the charging session management signaling scheme of the present application (such as shown above and below) is used in combination, that is, whenever the information of the vehicle capability is available, the charging electrode can be used. Or all signal transmission schemes or use specific methods.

In some embodiments, the charging point is configured and operable to monitor the state of the charging load presented by the charging device (eg, by monitoring the state of the SW2 switch shown in FIG. 2), and/or the actual amount captured by the charging device Current is used to determine when to disconnect the charging current supply after completing the signal transfer phase as described herein.

Thus, the charging point can utilize information regarding power management conditions to adjust the supply of charging power based on the rate of power consumption and/or any other desired parameters. Likewise, the charging point can be configured to receive (eg, on a wired communication link, and/or wirelessly) data indicative of power management commands and/or conditions for immediate use, and the charging point uses the data to adjust the charging power supply to the charging device.

In one variation, based on the conditions of the power supply network, the processor tool is configured to manage the timely segmented charging cycles by issuing a signal indicative of a start of a charge cycle and a signal indicative of terminating a charge cycle to the charging device. Alternatively, the processor tool can be configured to encode an allowable level of charge power consumption in a signal indicative of a start of a charge cycle.

In some embodiments, the data network 120 is a wireless data network, including: a cellular network, a Wi-Fi network, a WiMAX network, an EDGE network, a GPRS network, an EV-DO network, and an RTT network. , HSPA network, UTMS network, Flash-OFDM network, iBurst network, and any combination of the foregoing. In some embodiments, data network 120 includes the Internet.

As shown in FIG. 1, data network 120 can be communicatively coupled to charging device 102, service provider 112, charging point 106, power network 140, and/or battery switching station 108. However, in a possible embodiment, data network 120 is used to communicatively couple at least between central control system 112 and charging point and/or charging station 106.

For the sake of clarity, it is noted that only one charging device 102 (shown as a carrier in FIG. 1), a battery 104, a charging station 106, and a battery exchange station 108 are illustrated, and the power charging network 100 can include Any number of charging devices 102, batteries 104, charging stations 106, and/or battery switching stations 108, and the like. Additionally, the power charging point network 100 can include zero or more battery switching stations 108. For example, the power charging network 100 can include just one or more charging points 106. In some embodiments, any charging device 102, service provider 112, charging point 106, and/or battery switching station 108 include communication modules that can be used to communicate with one another via data network 120.

The power network 140 can include a generator 156, a power transmission line, a substation, a transformer, etc. (which facilitates the generation and transmission of power to various battery charging facilities).

Energy generated by one or more generators 156 may be distributed to home 130, charging point 106, and/or battery exchange station 108 via power network 140. The power network 140 can also include a battery, such as a battery, for example The battery 104 of the charging device 102, the battery at the battery exchange station 108, and/or the battery unrelated to the charging device 102. Thus, the energy generated by the generator 156 can be stored in these batteries and then taken out at a particular point in time when the energy demand exceeds the amount of energy that can be supplied by the power network.

Referring to Figure 2, in a typical charging session, charging point 106 can be coupled to charging device 102 (hereinafter carrier 102) using a standard connector or cable 14 as defined by the specifications of the IEC 61851 standard. As part of the connection 14, a preamble signal line 106p is coupled between the charging point 106 and the carrier 102, which allows the charging point 106 to control the charging session and adjust the supply of power charging power. Control unit 106c is used in charging point 106 to drive a voltage signal on front lead 106p and to measure voltage Va across resistive element R1 disposed on front lead 106p. The voltage signal applied to the front wire 106p is controllably changed by the control unit 106c by the switch circuit SW1, which arbitrates between the fixed 12V signal and the pulse ±12V voltage signal, and the pulse ±12V voltage signal is controlled by Unit 106c is modulated (PWM) to provide an indication of the allowable charging current that can be drawn by carrier 102 on power supply line 10. The control unit 106c can also control the electrical connection of the power supply line 10 to the connector 14 by means of a switch circuit 106r that is controllably coupled thereto.

The battery charge controller 102c is for receiving an indication from the charging point on the front wire 106p via the buffer circuit 102b in the carrier 102, and modifying the resistance on the preceding wire 106p by controllably changing the state of the switch circuit SW2. Typically the preamble signal is received via the diode D on the carrier side such that the battery charge controller 102c can actually only sense the positive portion of the preamble signal. The battery charge controller 102c measures the duty cycle of the signal received on the front conductor 106p, and thus activates the charger unit 102g to draw the allowable charging power to charge the battery 104 on the supply line 10.

The control unit can be implemented by any suitable combination of processing units (e.g., CPU, MCU, and the like) and memory units (e.g., RAM, ROM, EPROM, FLASH, and the like) well known in the art. (102c and 106c). The charging point 106 can be implemented using various methods described based on the schematic structure exemplified in FIG. 2 and the same as the applicant's International Patent Publication No. WO 2012/007784, the disclosure of which is hereby incorporated by reference.

Figure 3 shows a conventional charging dialog 30, for example, in accordance with the specifications of the IEC 61851 standard. Voltage map. Prior to establishing a connection (S1) with the carrier 102 using the connector 14, a charging point 106 (referred to as EVSE in the standard) supplies a fixed 12V signal on the front conductor 106p. The fixed 12V voltage is supplied via the fixed resistor R1, for example by setting the SW1 switch to the standby state. Once the connection between the charging point 106 and the carrier 102 is completed (S2), a circuit is closed and the front wire 106p is connected to the GND on the carrier side (ie, electrically grounded) via the series connection resistors R1 and R2, resulting in charging. The voltage Va observed at point 106 drops to 9V. The control unit 106c of the charging point 106 senses the voltage drop, thereby changing the state of the SW1 switch to the signal transmitting state and starting to drive the PWM signal on the front wire 106p (S3). The PWM duty cycle applied by the control unit 106c on the front conductor 106p indicates to the battery charge controller 102c the maximum allowable current that the charge electrode 106 can supply to the carrier 102 on the power supply line 10.

Next, the battery charging controller 102c of the carrier 102 connects the additional resistor R3 to the GND in the manner of the parallel resistor R2 by changing the state of the switch SW2 to issue a signal (S4) (hereinafter referred to as a state of charge) intended to draw current. . The battery charge controller 102c detects the PWM signal on the front conductor 106p and interprets it from allowing the charger 102g to draw an allowable charging current for charging the battery 104.

The parallel connection of the resistor R3 causes the control unit 106c of the charging point 106 to sense that the positive portion of the leading signal Va drops from 9V to 3V (or 6V, depending on the mode of operation). In response to this voltage drop, the control unit 106c of the charging point 106 connects the power supply V _(AC) on the supply line 10 to the connector 14 by changing the state of the switching circuit 106r (S5). The carrier 102 then begins to draw current from the charging point (S6) without exceeding the allowable maximum current indicated by the charging electrode 106 using the PWM preamble.

During the charging session 30, the charging point 106 may decide to change the allowable maximum current limit by changing the duty cycle of the PWM signal (S7). The battery charge controller 102c of the carrier 102 senses a change in this PWM signal on the front wire 106p and thus adjusts the maximum current drawn by the charger 102g (S8).

Whenever there is a need to terminate the charging cycle 30 on the side of the carrier 102 (e.g., in response to an instruction from the user 110), the battery charging controller 102c stops charging and current draw (S9) and is on standby by changing the state of the SW2 switch. The status indicates completion of the charging session (S10), thereby disconnecting the additional shunt resistor R3. This in turn causes the positive voltage of the PWM signal Va to go back up to 9V. The control unit 106c of the charging point 106 senses the voltage change of the signal on the front wire 106p and changes it. The state of the circuit 106r is turned off (S11), thereby turning off the power supply on the power supply line 10.

The charging session 30 is completed when the connection charging point 106 obtained by the charging cable connector 14 is removed from the mechanical and electrical connection of the carrier 102 (S12), and the voltage sensed by the control unit 106c on the front wire 106p Va returns to 12V. The control unit 106c of the charging point 106 senses the change in the voltage signal on the front wire 106p, and completes the charging session 30 by responding by stopping the PWM signal modulation (S13) and changing the state of the SW1 switch to the standby state.

While the standard charging procedure allows the charging point 106 to control the current level drawn by the carrier 102, it does not allow for the termination of the charging session by the charging point 106, or the interruption of the power supply to the charging current. The present invention, in some embodiments thereof, provides a power charging session management signaling scheme that allows the charging point 106 to indicate to the carrier 102 that the charging cycle will terminate, and thereafter, if possible, physically removes the charging cable connected thereto In the case of 14 resume charging (you can start a new charging cycle).

Some suitable power charging dialog management signaling schemes in accordance with possible embodiments may be used to signal that the charging point is intended to terminate the charging cycle to the carrier 102. FIG. 4 graphically illustrates a suitable power charging session management signaling scheme for use in the exemplary charging session 40, in accordance with a possible embodiment. Steps S1 through S6 in FIG. 4 (which open the charging dialog 40) are substantially similar to the same steps as defined in the standard as exemplified in FIG. 3 and described above, and will not be discussed again for the sake of brevity.

After steps S1-S6, the charging cycle 40a of the charging session 40 is initiated. In this example, when the charging point 106 is to terminate the charging cycle, its control unit 106c modifies the PWM duty cycle to 5% (S17). This particular duty cycle is reserved in the standard specification for signals to the carrier 102 that there is an additional sequence of signal paths between the charging point 106 and the carrier 102. After receiving such a signal, the battery charge controller 102c of the carrier 102 immediately stops the capture of the charge current and waits for the establishment of the series.

In this example, the carrier 102 having the battery charging controller 102c in accordance with the power charging session management signal transmission scheme of this embodiment stops current draw (S18), and then turns off the additional parallel resistor R3 (S19) to indicate charging. The control unit 106c of the point 106 terminates the charging cycle, which can then terminate the charging cycle 40a by turning off the power supply line 10 (S20).

The charging point 106 can issue a signal to resume the charging session 40 by modifying the duty cycle of the PWM preamble signal to be within the effective range of 8%-97% (S21). During the period between the end of the charging session S20 and the recovery of S21, the PWM is maintained at 5% duty cycle. Once the battery charge controller 102c of the carrier 102 perceives the modified duty cycle (S21), and if further charging is required, the battery charge controller 102c reconnects the shunt resistor R3 (S22) to indicate the control unit 106c of the charge point 106. It is intended to turn on a new charging cycle 40b and draw a charging current from the charging point. In response, control unit 106c reconnects power supply (S23) to power supply line 10, and the allowable charging current I _(AC) , represented by the PWM duty cycle of the preamble, is then captured by charger 102g.

Whenever needed, during the charging session 40, the control unit 106c of the charging point 106 can stop and resume the charging procedure multiple times by terminating the ongoing charging cycle and turn on the new charging whenever it decides to allow charging. cycle. For example, control unit 106c may receive a grid management command from power network 140 indicating that charging power should be disconnected on data network 120, and control unit 106c may issue a corresponding signal (S17) to instruct battery charging controller 102c to stop charging. The current is in response. During the charging session 40, the control unit 106c may receive a grid management command indicating that the charging is recoverable from the power network 140, if needed, and the control unit 106c indicates to the battery charging controller 102c that the charging is recoverable in response.

In some possible embodiments, data representing power grid management commands are transmitted from the power network 140 to the central control system 112 of the power charging point network 100 on the data network 120. The central control system 112 can be configured to analyze the power grid management commands received from the power network 140 and, based thereon, selectively instruct one or more charging points and/or charging stations 106 to temporarily stop the ongoing charging procedure (ie, terminate in progress) Charging cycle). In a similar manner, central control system 112 can selectively instruct one or more battery exchange stations 108 and/or a particular charger device used in battery exchange station 108 or home 130 to temporarily stop the ongoing charging procedure. Moreover, central control system 112 can be configured to selectively transmit power grid management commands based on a predetermined grid management policy (eg, as defined by a service provider or energy supply/control mechanism) without receiving such instructions from the power network to A charging point/station 106, a battery exchange station 108, and/or a charger installed in the home 130.

Additionally or alternatively, the charging point 106 can be configured to autonomously determine the adjustment of the charging power supplied locally to the carrier 102. For example, data representing power management conditions and/or commands may be stored in the memory of the charging point 106 and used by the charging point to locally terminate the ongoing charging cycle and begin a new charging cycle. Power management conditions and/or instructions may include charging A predetermined strategy used by the power station to locally determine the adjustment of the charging power supplied to the charging device.

Figure 5 illustrates another possible embodiment in which steps S1 through S6 of the charging cycle 50a of the start charging session 50 are also substantially similar to the same steps as exemplified in Figure 3 (as described above), and for the sake of brevity See will not be discussed here. Another possible charging session management signaling scheme of the present disclosure is illustrated in FIG. 5, the charging point 106 driving the voltage on the front conductor 106p to a fixed 12V by using, for example, a SW1 switch (ie, a RWM having a 100% duty cycle) ) to signal that it intends to terminate the charging cycle 50a (S27). In response, the voltage on the front conductor 106p becomes 3V/6V due to the parallel connection of the additional resistor R3 on the carrier side. The remaining steps (S19 to S24) in this example are substantially similar to the same steps as shown in Figure 4, as described above. The battery charging controller 102c supports the carrier 102 of this embodiment configured to stop the charging cycle 50a (S18) and to signal the control unit 106c of the charging point 106 to complete the charging cycle by turning off the shunt resistor R3 (S19). . The control unit 106c of the charging point 106 then turns off the power supply (S20). Resuming the charging session by initiating the new charging cycle 50b of steps S21 through S24 is substantially similar to the same program steps shown in Figure 4, as described above.

In Figure 6, which illustrates another possible charging session management signaling scheme of the present invention, the charging point 106 is configured to issue its intent by driving the front conductor 106p to a fixed -12V (0% duty cycle). The signal of the charging cycle 60a of the ongoing charging session 60 is terminated (S37). After sensing the signal (eg, if the sensing circuit behind the diode D senses a 0V signal), the battery charging controller 102c supports the carrier 102 of the signal transmission scheme of this embodiment to stop the charging cycle 60a ( S18) and disconnect the parallel resistor R3 (S19). In this example, since all the negative voltages applied by the control unit 106c are cut off by the diode D on the carrier 102 side and the resistance cannot be loaded, the control unit 106c of the charging point 106 cannot sense the leading resistance on the carrier side. A change in state in the circuit. Therefore, the change in the resistance connection state on the side of the carrier 102 does not affect the signal on the wire 106p before the charging electrode 106 side, and thus is not sensed by its control unit 106c. In this case, the control unit 106c of the charging point 106 may turn off the power supply after the battery charging controller 102c of the carrier 102 is allowed to terminate one of its current draws for a predetermined predetermined delay time _delay (S40).

The beginning of the new charging cycle 60b in steps S21 through S24 (to restore the charging session 60) is substantially similar to the same steps shown in Figure 4, as described above (between the termination of the charging session S37 and the recovery S21, the PWM signal Keep at -12v level). Start charging in Figure 6. Steps S1 through S6 of charging cycle 60a of dialog 60 are also substantially similar to the same steps shown in Figure 3, as described above.

In FIG. 7, which illustrates yet another possible charging session management signal transmission scheme of the present invention, the control unit 106c of the charging point 106 is configured to drive the signal on the front conductor 106p to a fixed 0V (S47) up to one. The shortest period _Tdelay is scheduled to signal its intention to terminate the charging cycle 70a in the charging session 70, and then the charging power supply is turned off (S50). The battery charging controller 102c is configured to support the carrier 102 of the signal transmission scheme of this embodiment to detect that the signal is transmitted as a wire extraction event, and to stop the charging cycle 70a (S18) and turn off the parallel resistor R3 (S19) in response. In this example, when the control unit 106c of the charging point 106 wants to start a new charging cycle 70b and resume charging, it drives the preamble signal to 12V (S51) and then uses the conventional PWM preamble signal to the battery of the carrier 102. The charge controller 102c indicates that the chargeable conversation can be resumed. The charge controller 102c of the carrier 102 supports the signal transmission scheme of this embodiment, and then connects the parallel resistor R3 (S52) and drives the pilot voltage to 6V (or 3V). The control unit 106c of the charging point 106 can be configured to determine whether the particular carrier 102 has been correctly detected by testing the maximum voltage level of the reapplied PWM signal to be actually 6V (or 3V) (and not 9V). The 0V signal is detected as a disconnect event.

Steps S1 through S6 of turning on the charging cycle 70a of the charging session 70 in FIG. 7 are also substantially similar to the same program steps shown in FIG. 3, as described above.

It should be noted that some of the signal transmission methods described above are not defined in the standard, and thus some charging devices may support all, part, or none of these methods. The support of each of these methods depends on the particular implementation as defined by the respective manufacturer of the charging device.

To overcome this limitation, in a possible embodiment, information can be sent from the onboard communication module 114 of the charging device 102 to the charging point 106 or the service provider 112 to identify the exact type of charging device 102 currently connected to the charging point 106. (eg the brand and model of the electric vehicle). Based on the identification information, control unit 106c of charging point 106 can learn a particular signaling scheme to manage the charging session, for example, by initiating one or more charging cycles (if needed) in the charging session. The signal transmission scheme used may be any of the above methods or any other method. For example, certain electric vehicle-specific new and different signal transmission schemes may be selected based on the identification information received from the vehicle. The mapping type of the relevant type of charging device together with the specificity of its support The charging session management signaling scheme can be stored on an onboard communication module that is disposed in a carrier, an operating server (not shown), or a charging point 106.

In some embodiments, the onboard communication module 114 of the charging device 102 communicates directly with the charging point 106 via wired or wireless communication and provides it with information of a particular model and brand of the charging device 102. The charging point 106 can utilize this information to determine the type of charging session management signaling scheme supported by the battery charging controller 102c of the charging device 102 to be served. Alternatively, the onboard communication module 114 of the charging device 102 can be used to directly indicate to the charging point 106 and/or the central management system 112 a particular charging session management signaling scheme supported by the carrier 102.

For example, the charging session management signal transfer scheme supported by the charging device 102 can be transmitted by the onboard communication module 114 to the charging point 106 and/or the central management system 112 on the data network 120. In a possible embodiment, the charging point includes a communication module 106t (wired or wireless), and the onboard communication module 114 can be used to communicate directly with the charging point (eg, wirelessly using Wi-Fi, Bluetooth, or A ZigBee communication unit, or a wired communication using a data machine, a network card, or a serial or parallel data bus, and providing a charging session supported by the charging device during (or after) the proximity of the carrier 102 to the charging point 106 Manage data for signaling schemes.

8A is a diagram showing an event tracking of a possible embodiment in which data representing a signal transmission scheme supported by charging device 102 is transmitted to charging point 106 prior to or during the start of a charging session. In this example, the charging device 102 can transmit the data (80) indicating the supported charging session management signal transmission scheme along with the identification data (eg, device manufacturer and model, and/or serial number) to any time prior to initiating the charging session. Service provider 112 (labeled as control center in Figure 8A).

Referring now to FIG. 1, in some embodiments, service provider 112 hosts and manages a repository 44 containing complex data records 42 each associated with a particular charging device 102. For example, each data record 42 may include identification information 42a about the charging device 102 and/or its user 110, information 42b indicating a charging session management signal transmission scheme supported by the carrier 102, and additional information 42c that may be needed ( For example, the history of previous charging events, information about rechargeable batteries previously used by charging devices, and the like). The service provider 112 can be used to receive the information 42a, 42b, and 42c transmitted from the charging device 102 and record it in a particular data record 42 in the database 44.

Whenever the charging device 102 approaches the charging point 106, it can send a charging device The identification information (81) of 102 is set to the charging point 106. Upon receipt of the identification data, the charging point 106 can transmit a request to the service provider 112 (82) to provide the data 42b indicative of the charging session management signal transmission scheme supported by the charging device 102 based on the received identification information. The service provider 112 can then search the database 44 for the data record 42 associated with the charging device 102, and issue data 42b indicating the charging session management signal transmission scheme supported by the charging device 102, and possibly the charging device 102 and / Any additional data 42c of its battery 104 is responsive to charging point 106 (83).

Optionally, the service provider 112 transmits the entire data record 42 to the charging point 106 as received in the request 81 that is paired with the user 110 and/or the charging device 102.

Alternatively, before or during the start of the charging session, the charging device 102 transmits the data 42b indicating the charging session management signal transmission scheme supported by the charging device 102 to the charging point 106 (84). The charging point can send the received information to the service provider 112 to update the database 44 (85).

In some possible embodiments, the charging point 106 includes a user interface module (106m in FIG. 1) that enables it to receive identification credentials of the user 110 (eg, using an RFID card, smart card, or biometric tag). . The charging point 106 can be used to receive identification information from the identification credentials and optionally authenticate it with the service provider 112 (or operator server). For example, the identification information sent from the charging point 106 to the step service provider 112 in step 82 of FIG. 8A may include identification information of the user 110 of the charging device 102, and the database 44 may be configured to be based on the received user 110. The identification information is used to search for a particular data record 42 of the respective charging device 102.

The identity credentials received via the user interface module (106m) at the charging point 106 may also include information on the charging device 102 of the user 110 and its brand, and/or indicate a charging session supported by the charging device 102. Management information 42b of the signal transmission scheme. Alternatively, the charging point 106 can obtain this information by communicating with the lead library 44 and an operator server (not shown) that can be paired between the user 110 and the vehicle 102 based on the received identification information.

The charging point 106 then utilizes a particular signaling scheme of the particular supported charging session based on the data (42b) received from the service provider 112 and/or the power network 140 to signal any interruption in the charging session (83). For example, once a connection to the charging device 102 is established (S2), the charging point can indicate to the charging device 102 (S3) an allowable charging that can be retrieved from the power grid. The power, and charging device 102 can then indicate its intent to connect to the charging load (S4). Thereafter, the charging point 106 is connected to the charging power (S5) and the charging device 102 draws the allowable charging power, and whenever the charging point 106 is required to be disconnected from the charging power, it will indicate the signal transmission supported by the charging device 102 as such. One of the schemes (S17, S27, S37, or S47). In response, the charging device 102 will be disconnected from the charging load by changing the state of the SW2 switch and indicating the situation (S19). During the charging session, any number of charging cycles may be terminated (S17, S27, S37, or S47) and restarted (S21 to S24) as needed by central control system 112 and/or power network 140 until the battery of the charging device It has been fully charged. Referring to FIG. 8B, in a possible embodiment, where the charging device 102 is connected thereto, the charging point 106 can be used to test some or all of the charging session management signaling schemes, and to record the response of the charging device 102 (ie, if issued) When the signal is signaled, it stops charging and resumes charging after re-applying a signal indicating the charge before charging for future use with that particular vehicle. For example, such a charging session can include providing identification information (86) regarding the user 110 and/or its charging device 102, followed by standard steps (S2 through S5) of initiating the first charging cycle. Thereafter, the charging point can issue a signal indicating that the charging cycle is required to be terminated (S17 or S27) by changing the duty cycle of the PWM signal to 5% or 100%. If the charging device 102 conforms to any of these signal transmission schemes, it will be represented by changing the state of the SW2 switch (S19), and the charging point 106 will then record data indicative of the charging session management signal transmission scheme supported by the charging device 102. And therefore continue to charge the conversation. Recording data relating to the signal transfer scheme supported by the charging device 102 can also be sent (87) to the control center 112 for recording in the database 44 for future use at any of the same or other locations of the charging point 106.

If the charging device 102 does not comply with the signal transmission scheme of 5% or 100% duty cycle (S17 or S27), the charging point may further test whether it supports a 0% duty cycle or a 0V signal transmission scheme (S37 or S47). If the charging carrier 102 conforms to any of these signal transmission schemes by removing the charging load (S18) and/or disconnecting the R3 resistor (S19), the charging point 106 records information indicative of the supported signaling scheme and thus continues Charging conversation. Recording data relating to the signal transfer scheme supported by the charging device 102 can also be sent (87) to the control center 112 for recording in the database 44 for future use at any of the same or other locations of the charging point 106.

Some charging devices 102 may not support any signal transmission scheme for this application. That is, such charging device 102 may not accept the termination charging session controlled by charging point 106, and thus may require a physical plug other than charging cable 14 and its reinsertion to re-open the charging. Electrical program. The charging point 106 supporting this type of charging device 102 should take this limit into account and thus modify the charging schedule. Such modifications may include maintaining a minimum current supply to the particular charging device 102 throughout the charging session.

Thus, in some possible embodiments, the charging session can include a plurality of charging cycles in which the charging power between one or more charging cycles is reduced to a predetermined minimum charging power (ie, instead of temporarily turning off the charging power). As explained above, a limited number of power disconnections may be allowed for certain types of electric vehicles, and thus the charging device 106 of the present application may be configured to reduce charging power to a predetermined minimum value in response to the central control center 112. And/or grid management instructions received by the power network 140.

The above examples and description are of course provided for illustrative purposes only and are not intended to limit the invention in any way. As will be appreciated by those of ordinary skill in the art, the present invention can be practiced in many different ways using more than one of the techniques described, without departing from the scope of the invention.
